Growth kinetics of solution grown Zn0.2Cd0.8S thin films

The authors describe the nucleation and growth kinetics of Zn0.2Cd0.8S thin films grown at about 900C by the solution growth method on various substrates like glass, tin-oxide coated glass, quartz and p-Si studied by using Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Electron diffraction techniques. The appearance of fiberous structure of Zn0.2Cd0.8S films grown on glass and tin-oxide coated glass in contrast to the appearance of spherical grains of Zn0.2Cd0.8S films grown on quartz and p-Si at smaller thickness, clearly shows the role of the substrates in the growth of the films. With increasing thickness, the influence of the substrate surface decreases and the more stable crystalline phase appears
